Description

Brenner zur Erbitzung von Nieten. Bei den bisher bekannten Nietwärmöfen mit einer einzigen, das vorzuwärmende Niet bestreichenden Flamme stellt sich der Nachteil ein, daß die zu erhitzenden Niete nur unvollständig von der Flamme umspült werden, so daß eine verhältnismäßig lange Zeit zur vollen Erhitzung der Niete und .eine beträchtliche Gasxnengeerforderlich sind.Burner for the acquisition of rivets. With the previously known rivet heating furnaces with a single flame sweeping the rivet to be preheated, the Disadvantage is that the rivets to be heated are only incompletely washed by the flame be, so that a relatively long time to fully heat the rivet and . a substantial amount of gas is required.

Gemäß der Erfindung wird die Erhitzungszeit und daher auch die Gasmenge dadurch vermindert, daß die Niete statt von einer runden Flamme durch die Nietschäfte ihrer ganzen Länge nach bespülende Flammen erhitzt werden.According to the invention, the heating time and therefore also the amount of gas reduced by the fact that the rivet instead of a round flame through the rivet shafts Flames that wash over their entire length are heated.

Zu diesem Zweck ist die Anordnung derart getroffen, daß im Mundstück des das Gasgemisch zuführenden Brenners mindestens zwei zum Nietschaft parallele Gasauslaßschlitze vorgesehen sind, so daß die Flammen parallel zum Nietschaft austreten und ihn gleichzeitig an allen Stellen rasch erwärmen.For this purpose, the arrangement is such that in the mouthpiece of the burner supplying the gas mixture at least two parallel to the rivet shank Gas outlet slots are provided so that the flames emerge parallel to the rivet shank and at the same time quickly warm it up in all places.

Zweckmäßig ist das Brennermundstück im Einklang mit den Gasauslaßschlitzen rechteckig gestaltet.The burner mouthpiece is expediently in line with the gas outlet slots designed rectangular.

Die Zeichnung zeigt eine Ausführungsform des Erfindungsgegenstandes.The drawing shows an embodiment of the subject matter of the invention.

Abb. i stellt den Brenner im wagerechten Längsschnitt dar.Fig. I shows the burner in a horizontal longitudinal section.

Abb.2 zeigt eine schaubildliche Ansicht des Mundstückes.Fig.2 shows a perspective view of the mouthpiece.

Das Mundstück 25 besitzt zwei parallele Schlitze 27, 28. Mittels eines Rohrnippels 23 ist das Mundstück 25 an eine Mischkammer 24 angeschlossen, in die die zur Zuführung des Sauerstoffes uud Azetylengases dienenden Leitungen münden, welche durch einen Hahn 29 gemeiüsam absperrbar sind. In der Offenstellung des Hahnes gelangen die Gase durch die Kanäle 3o, 3 i zur Mischkammer. Hierbei strömt das eine Gas am Umfang 3o' eines verjüngt auslaufenden Einsatzes, das andere Gas durch die mittlere Bohrung 3 i' dieses Einsatzes zum Rohrnippel, um in der anschließenden Mundstückkammer sich innig zu mischen und hierauf durch die Schlitze 27, 28 auszutreten.The mouthpiece 25 has two parallel slots 27, 28. By means of one Pipe nipple 23, the mouthpiece 25 is connected to a mixing chamber 24 into which the lines serving for the supply of oxygen and acetylene gas open, which can be shut off jointly by a tap 29. In the open position of the cock the gases reach the mixing chamber through channels 3o, 3i. One thing flows here Gas on the circumference 3o 'of a tapered insert, the other gas through the middle hole 3 i 'of this insert to the pipe nipple in order to be in the subsequent Mouthpiece chamber to mix intimately and then to exit through the slots 27, 28.

Befindet sich das Niet R1, wie dies strichpunktiert in Abb.2 angedeutet ist, vor der Fläche 26, so bespülen die bei 27, 28 austretenden Flammen den Nietschaft seiner ganzen Länge nach.Is the rivet R1, as indicated by dash-dotted lines in Figure 2 is, in front of the surface 26, so the emerging at 27, 28 flames wash the rivet shank along its entire length.

Die Anzahl der Gasauslaßschlitze kann ebenso wie die Art ihrer Anordnung den jeweiligen Bedingungen gemäß abgeändert werden.The number of gas outlet slots as well as the way in which they are arranged can be be modified according to the respective conditions.

Die Brenner können aus Kupfer, Metallguß, Steatit oder einem anderen feuerbeständigen Stoffe hergestellt sein.The burners can be made of copper, cast metal, steatite or another fire-resistant materials.
